Hello,

I am trying to remove a RadDocumentPane from a region when its closed, but I cant find a way to catch the close event in my viewmodel?

Whats the best approach to accomplished this with the Docking control?

 

Marcel

 

It's Telerik UI for WPF 2014.3.1202.40.

There is a  RadCartesianChart on screen. Once user clicks on outside region of the chart, the track ball disappears due to losing keyboard focus.

Is it possible to keep the track ball inside chart in this case? It still has logical focus anyway.

Thanks.

Say I have a Diagram that is 1920x1080.  I call ExportToImage with an enclosingBounds of (0, 0, 1920, 1080), a returnImageSize of (1920,1080), and a dpi of 384.

 I get an image that is 7680 x 4320.  Is that expected?  I am (perhaps naively) expecting to get an image that is 1920x1080, based on the value of the returnImageSize parameter.

 Thanks!

We are using the TextControl (http://www.textcontrol.com) in an WinForms application used by more then 40.000 employees.
Now we are migrating the application to WPF.
We realize a problem on HD Displays, where standard build-in dialogs like Search and Replace, Spellchecker, Font Format dialogs etc. are too small - maybe because standard MVC dialogs are still used.

 

What about the Telerik RichTextBox control?
Are all Build-In dialogs scaling on HD-Displays correctly?

 

 

Hi,

 I tried to implement the MouseLeftButtonDown event and the CellDoubleClick event on a style:

 

The "CellDoubleClick" event works fine but the "MouseLeftButtonDown" event doesn't work! I tried each event alone in the style and the MouseLeftButtonDown never works!

In the class "GridViewHeaderCell" there is no event accessible for MouseLeftButtonDown, there is only a method called "OnMouseLeftButtonDown" My guess is that the event MouseLeftButtonDown (or MouseDown) is already handled somewhere else...

If I want to use the method "OnMouseLeftButtonDown" I have to create a new ​child class that the parent is "GridViewHeaderCell". But I don't know where to allocate the new class in the code. Is there a event like "AutogeneratingCoumn"?

Is there any other options possible to support the MouseLeftButtonDown event or a single click?

 

 

 ​

 

 

 

I'm looking for a way for an autogenerated propertygrid checkbox item to disable (IsReadOnly/ReadOnlyEditorState) other items in the grid.

Is there an event or a isSelected for the generated checkbox available somehow?

 

Thank you,

Garrick

 

I have a bread-crumb, i make a control-template for this bread-crumb

(i do it automatic in the blend- "EditTemplate"->"Edit a copy")

when i used this template my history pop-up is always empty, (the history in the model - correct, but on the view its empty!).

thenk you for helping!

Following your Serialize a Databound Diagram article
I was wondering whether the RadDiagram Serialization/Deserialization system supports serialization of a collection within the GraphSource Nodes. In particular I am interested on using an ObservableCollection:

 

Could I possibly Serialize/Deserialize the ObservableCollection in the OrgItem?

If that is possible how should i serialize/deserialize the collection in the GraphSource?

 

Many thanks in advance,

Christos

Hi guys,

I have a user control which contains a RadPanelBar with 5 RadPanelBarItems and within each item is a grid (total 5 grids). The issue I am having is that that the grids take around 3-4 seconds to render. Each grid consists of about 10 rows, 16-17 columns, 1-2 groupings. The RadPanelItems are set to expanded by default. Each grid has a row loaded event handler attached and data is bound in XAML via CollectionViewSource objects. I've checked out the degraded performance section in the help file so I tried setting the Grid's Rows, RadPanelBar, RadPanelBarItems and GridView to fixed sizes. I'm binding to an ObservableCollection of BindingLists so not sure if this affects performance. Not using converters, cell templates or alternate row style.

I've used JetBrains dotTrace performance to determine which functions are taking the longest to load. I've managed to narrow it down to the MeasureOverride function from the GridViewCellsPanel class, specifically it goes down to the GenerateAndMeasureChildrenForRealizedColumns() -> GenerateChildren() functions. My question is that is there anyway I can do to reduce the load times of these grids? This app supercedes our old app which was written in C# WinForms, however loads instantaneously. I've attached a screenshot of my grids setup (the rest of the grids require me to scroll down the view).

Cheers,

Tim.
